Yeah, I used to see this a lot too (until we made solib-absolute-prefix
automatic in our tools).  Unfortunately there is no clear hook to
figure out if a target is remote or local; and a lot of people actually
do use gdbserver to talk to localhost... and then there's no way to
know if it's the same root or not.
